Hi
Sailing 30 yrs ago we used to wax and polish hulls to maintain a protective and as gloss a surface as possible. However some say that anything that beads water such as wax causes more drag than a smooth surface that water will sheet over.
Note Racing rule 53 " SKIN FRICTION
A boat shall not ejest or release a substance, such as a polymer, or have special textured surfaces that could improve the character of the flow of water inside the boundary layer."
I believe this is not intended to prevent the use of protective treatments such as wax but does not allow the use of chemicals that can leach into the water to give advantage.
Is there anything in this idea that protective treatments might affect the boundary layer differently to a high gloss natural surface?
Discussion on effects on polar molecule alignment, fresh vs sea water etc please?
Regards,
Ken
